RADIATOR.

Application led March 31, 1919. Serial No. 286,302.

To all whom t may concern: n

Be it known that I, IRA C. DoUeLss, a citizen of the United States, residing in Rochester county of Monroe, and State of New Yor have invented certain new and useful Improvements in Radiators; and I do declare to following to be a full, clear, and exact description of thesame, taken in connection with the accompanying drawings, forming a part of this specification.

My invention relates to radiators, espelciall to that class of radiators through whic Huid such as steam or hot water 1s circulated for heating the interior of houses or other buildings. The principal object of my invention is to construct an im roved radiator of this kind, cheaply of s eet metal andl of such a form that its exterior surface is adapted to have a very thin coat vof enamel applied thereto.

More specifically the object of my invention is to construct a radiator of sheet metal in two parts which may be welded together along their Yedges and which is so constructed Ias to secure perfect drainage, and which is substantially seamless. v

Referring to the drawings;

Figure 1 is a side elevation of a radiator constructed according to my invention.

Figure 2.is an end elevation of the same,

Figure is -a horizontal section throughl the radiator shown in Fig. 1, a part being broken away, and

Figure 4 1s a view similar to Fig. 3, showing a slightly modified form of construction. 1 p Similar reference characters refer to the same parte in all the figures of the drawings A radiator constructed accordin to my invention comprises two parts l and 2, Fi ures 1, 2 and 3 stamped from sheet met, preferably steel into the form clearly shown inv Figure 3. The parts 1 and 2 are duplicates and the corrugations 3 andA 4 are provided to increase the .radiating surface and need not be of the exact form and size illustratedherein. The two arts 1 and 2 are placed together with their outer edges in register and welded together along the-edges electrically or by other suitable means, as indicated at 5. The ends of the radiator maybe made with a plane surface as indicated in Figure or formed with a corrugationj 6 as indicated in Figure 4 to increase the radiating surface. The radiator is Su ported on legsI 7 which are secured to t e body portion by'weldin or other suitable means. The bottom of t e radiator. is constructed in substantially one plane to secure perfect drainage and-is adapted to be connected with. a boiler or other suitable source of steam or hot water by means of the conducting pipes 8 and 9 which may be provided with the stop cocks 10 and 11 for closing the pipes when the heat is not desired.

It lwill be noted that my improved radiator can be cheaply made b stamping the parts 1 and 2 and welding t e seams l5 electrically. A radiator v thus constructed of sheet steel is sanitary since no Shar corners or deep crevices are formed and i desired a thin coating of enamel or glass, as indicated at 27, may be ap lied to its surface to improve sanitar con itions and the general appearance o the radiator. It is im possible to enamel the surface of a radiator by the usual processes which is cast or compound of separate units.

'If desired, I may employ means for reinforcing the material of my radiator as clearly indicated in Figs. 3 and 4 of the drawings. To this end, one or more ri 'd bars 28 of steel or other suitable materia are secured to the inwardly curved parts of the walls of the radiator by welding on other suitable means. The braces or bars 28 are applied to the arts 1 and 2 'before said parts are secureg to each other, and when. the radiator is completed lie within the radiator and do not aiect its appearance or sanitary ualities.

It w11l e noted -that my radiator is constructed of sheet steel in which the seams 'are electrically welded making it substantially seamless. Such a radiator presents a line grained smooth surface to which enameli'ng can be readily applied andvwhich can be treated both internally and externally with rust proofing processes commonly in use.

Having described lmy invention what I claim and desire to secure by Letters Patent is' f .Y i

1. radiator constructed oi two sheet metal parts formed with corru ations to increase their surface areas an joined together at their edges to form a closed chamber adapted to contain a fiuid, and means secured to the corrugations of each of said parts Within the chamber for reinforcing 5 its Walls.

2. A radiator constructed of two sheet metal parts formed with oorrugations to increase their surface areas and joined toether at theiredges to form a closed cham- 10 er adapted to contain a fluid, and reinforcing bars Welded to said corrugations within the chamber.

3. A radiator constructed of two similar sheet metal parts formed with corrugntions and smoothly joined together at their edges to form a closed chamber adapted to contain a fluid, and reinforcing bars extending transversely of said corrugations and secured thereto within the chamber.
